Abstract

Stainless steel, polymethylmethacrylate and polytetrafluoroethylene coupons were analysed for surface topographical and adhesion force characteristics using tapping mode atomic force microscopy and force-distance microscopy techniques. The two polymer materials were surface modified by polishing with silicon carbide papers of known grade. The struvite scaling rate was determined for each coupon and related to the data gained from the surface analysis. The scaling rate correlated well with adhesion force measurements indicating that lower energy materials scale at a lower rate. The techniques outlined in the paper provide a method for the rapid screening of materials in potential scaling applications.

FORMAzol as an RNA storage medium: a cautionary note when performing RT-PCR.

The labile nature of RNA demands careful procedures for its extraction, purification, and storage. Generally, RNA is solubilized in aqueous buffers or organic solvents, or precipitated with alcohol and then kept at -20 degrees C or colder. A commercially available product for RNA storage is FORMAzol(R) (Molecular Research Center). We began using FORMAzol because the Application Notes from the Product Description sheet claims that reverse-transcription (RT) is not inhibited so long as FORMAzol does not exceed 5% (v/v) in the reaction mix. This is ostensibly more convenient than having to precipitate RNA, resolubilizing it in water or buffer, and then proceeding with RT-PCR. However, amplicon yields for glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were poor when using RNA directly from FORMAzol, even though its final concentration was typically much less than 5%. By contrast, satisfactory RT-PCR products were obtained with RNA stored frozen in water or that had been resolubilized from alcohol precipitates. When RT-PCR was then performed on ethanol-precipitated and resolubilized RNA from FORMAzol, yields of GAPDH amplicons were acceptable. Although a revision to the FORMAzol Product Description sheet is now available at the manufacturer's website (http://www.mrcgene.com/formazol.htm), if users of the product implicitly follow the directions found in the package insert sheet-not being aware of the inhibitory effects of formamide (the denaturant in FORMAzol)-unsatisfactory results may be obtained from RT-PCR experiments. It is suggested that FORMAzol only be used for RNA storage and that RNA be precipitated with alcohol, washed, and resolubilized prior to use.

A hybrid liquid-phase precipitation (LPP) process in conjunction with membrane distillation (MD) for the treatment of the INEEL sodium-bearing liquid waste.

A novel hybrid system combining liquid-phase precipitation (LPP) and membrane distillation (MD) is integrated for the treatment of the INEEL sodium-bearing liquid waste. The integrated system provides a "full separation" approach that consists of three main processing stages. The first stage is focused on the separation and recovery of nitric acid from the bulk of the waste stream using vacuum membrane distillation (VMD). In the second stage, polyvalent cations (mainly TRU elements and their fission products except cesium along with aluminum and other toxic metals) are separated from the bulk of monovalent anions and cations (dominantly sodium nitrate) by a front-end LPP. In the third stage, MD is used first to concentrate sodium nitrate to near saturation followed by a rear-end LPP to precipitate and separate sodium nitrate along with the remaining minor species from the bulk of the aqueous phase. The LPP-MD hybrid system uses a small amount of an additive and energy to carry out the treatment, addresses multiple critical species, extracts an economic value from some of waste species, generates minimal waste with suitable disposal paths, and offers rapid deployment. As such, the LPP-MD could be a valuable tool for multiple needs across the DOE complex where no effective or economic alternatives are available.

Temperature-induced sedimentation to dispersion of ionic vesicles.

We present a temperature-induced sedimentation/dispersion transition of ionic vesicles in the system of alkyldimethylamine oxide hemihydrochloride (CnDMAO.1/2HCl) with a hydrocarbon chain length of 12-16 (n = 12, 14, and 16) and sodium 2-naphthalenesulfonate (NaNphS). The temperature-sensitive sedimentation/dispersion of ionic vesicles took place around a temperature of 50 degrees C, which was weakly dependent on the alkyl chain length. The combined effect of the thermally induced dissociation of the counterions from the vesicle and a hydrogen bonding between the nonionic and the cationic head groups is likely to be responsible for this unique behavior.
